I'm running into the same issue (I'm using logback 0.9.21).
I tried to configure Logback manually using the JoranConfigurator.
Well, I started extending the JoranConfigurator trying to avoid the
call to the method ContextUtil.addHostNameAsProperty() in the
ConfigurationAction class that is the one causing the issue but it
looked I needed to extend a few classes and started to look messy.
At the end I took a different approach. Just created the ContextUtil
class in my webapp project in the same package as the original one so
mine would be picked instead of the other.
This is the code I put for that class ... (basically removing the use
of java.net.InetAddress class)
package ch.qos.logback.core.util;
import ch.qos.logback.core.Context;
import ch.qos.logback.core.CoreConstants;
import ch.qos.logback.core.spi.ContextAwareBase;
public class ContextUtil extends ContextAwareBase {
public ContextUtil(Context context) {
setContext(context);
}
/**
* Add the local host's name as a property
*/
public void addHostNameAsProperty() {
context.putProperty(CoreConstants.HOSTNAME_KEY, "yourhostname");
}
}
Hope it helps.
